The film Arrival showed Wolfram Language code in action analysing alien logograms. A recent
blog describes some details and
mentions
a live-coding video by Christopher Wolfam. See also Stephen Wolfram's
blog post.

The logograms appear to be hand drawn in ink, and I seek help from the community to reproduce them via the Wolfram Language. Some examples follow.

Three Questions
What techniques can you suggest to improve the match between computer-generated logograms and those which appear in the movie?
Specifically, how to improve:
1) background circular strokes
2) blobs
3) tendrils
